Guerrilla

Provides aribtrary monkey patching in Rust. Please do not use this crate for anything outside of testing.
It will not end well.

Can patch (almost) any function in Rust (free, associated, instance, generic, etc.). Can not patch anything from std.

Usage

externcrate guerrilla;#[inline(never)]fnsay_hi(name:&str){println!("hello, {}", name);}fnmain(){// Variadic generics would be wondeful so we could have a [guerrilla::patch]let _guard =guerrilla::patch1(say_hi,|name|{// So sneaky... like a sneaky sneaky snekprintln!("bye, {}", name);});// [...]// Thousands of lines codes further in the project// [...]say_hi("Steve");// Once the guard is dropped the patch reverts the function to its original// behavior.drop(_guard);say_hi("Bob");}
